Three Jersey City plainclothes police officers collared an armed robbery suspect Friday within about 15 minutes of the crime, according to police reports.

The officers, part of the Violent Crimes Unit, were in an unmarked police car when a call came in at 10:15 p.m. of an armed robbery in the area of Brinkerhoff Street and Monticello Avenue, said the police report.

Charged was Carl Blackwell, 20, of Jersey City following a foot chase, reports said.

The arrest came after the officers spotted a man on a bike matching the description of the person wanted in connection with the earlier armed robbery.

The police vehicle pulled up alongside the cyclist, and an officer stepped out and identified himself as Jersey City Police.

According to the police report, the man later identified as Blackwell then dropped his bike and began to run north of Monticello Avenue.

The police officer gave chase while the other two officers in the vehicle drove up ahead.

The officer on foot said in the report that Blackwell was seen reaching into his front pants pocket attempting to remove an object. The officers caught Blackwell and he was arrested after a brief struggle.

Police found a black Rohm .22 caliber revolver, loaded with 5 bullets, in Blackwell’s possession. Blackwell was later identified by the victim of the earlier robbery.

He was transported to the Jersey City Medical Center for a minor cut and was cleared for incarceration and released said the report.
